WebIt's a familiar function notation, like f (x,y), but we have a symbol + instead of f. But there is other, slightly more popular way: 5+3=8. When there aren't any parenthesis around, one tends to call this + an operator. But it's all just words. WebGenerally, the gradient of a function can be found by applying the vector operator to the scalar function. (∇f (x, y)). This kind of vector field is known as the gradient vector field.
